Slideshow now has it's own web page:
http://www.plt-scheme.org/software/slideshow/
The most important link on that page is "Examples", from which you can
access the source (and generated PDF) for five talks and two sets of
course slides --- more than 30k lines of example Slideshow code!
The page also contains a link to a paper about Slideshow:
"Slideshow: Functional Presentations"
Robert Bruce Findler and Matthew Flatt
ICFP 2004 (to appear)
The paper is mostly a tutorial. It covers fewer constructs than the
slide-format tutorial that is distributed with Slideshow, but it
provides more explanation and rationale for the covered constructs.
Let me know if you have any trouble downloading an example or getting
it to run.
